If Starbucks manages to perfect this, it could be a big hit for the coffee retailer. They are working on a latte that will taste like Guinness.


Coffee that tastes like stout beer? Sounds perfect doesn't it?


They will use a dark barrel latte, which is made up of flavored syrup to mirror the taste of a Guinness.


It will have whipped cream and a dark caramel sauce.


It's available at some test markets now, but there's no word on when it will be available worldwide.


Imagine drinking this in the morning!
